Abstract

This work was aimed to prepare new monomer [ E)-1-(4-aminophenyl)-3-(4-hydroxyphenyl) prop-2-en-1-one] and three types of poly (ester-amide) polymers. New monomer is Chalcone compound α,β- unsaturated ketone contain functional group(-CO-CH=CH-) of presence system α,β- unsaturated carbonyl group. It is prepared by condensation aryl ketone with aromatic aldehyde with presence of suitable condensation agents which called Aldol condensation. Monomer reacted with (phthalic anhydride ,maleic anhydride ,salicylic acid and succinic anhydride) Via solution poly condensation reactions to yield three types of polymers. The prepared monmer and polymers were characterized by [(FT.IR-spectra, Nuclear magnetic resonance 1H.NMR-spectra , 13C.NMR-spectra and Differential scanning calorimetry (DSC)] All the polymers showed good thermal stability and good data of glass transition temperature (Tg). The results revealed that poly (ester-amide)s were successfully prepared by giving good spectrum which improved the existed amide functional group (-CONH-) and ester functional group (-COO-) in spectrum of each prepared polymer, furthermore the existed chalcone functional group(-CO-CH=CH-) is improved in spectrums of monomer.
